Description
Technical field
The present invention relates to a kind of fixed sterile types to drink water storage apparatus, belongs to the water quality advanced processing skill of Drinking Water
Art field.
Background technique
Water pollution is mainly caused by the pollutant that mankind's activity generates, it includes industrial pollution source, agricultural pollution source with
Domestic pollution source three parts.Increasingly the water pollution aggravated constitutes significant threat to the living safety of the mankind, and it is strong to become the mankind
Health, the major obstacles of economy and society sustainable development.It investigates according to authoritative institution of the world, is at least made because drinking unhygienic water every year
Dead at global 20,000,000 people, therefore, water pollution is referred to as " world's number one killer ".Currently, water environment is exacerbated, sternly
Weight threat to life continue, especially when happen suddenly natural and man-made calamities when more so.More poor and backward area, drink is to completely
Trust that water is even almost luxurious for general public.If can make the common people that can all drink with simple, cheap, efficient means
To completely trusting water, when for how immeasurable beneficence！
Domestic and international most of waterworks are so far still using precipitating, filtering, the outmoded process of chlorination, by rivers
Water or underground water are simply processed into drinkable water.However, spreading unchecked and pouring in face of trade effluent, rural sewage and sanitary sewage wildness
Life water source, waterworks can't bear the heavy load helpless.Along with tap water from water factory through water transfer pipe network and high-rise water storage
Case reaches and adds pollution brought by drinking water terminal, and it is health that municipal tap water dare not have been said.Especially, tap water adds
Although chlorine can be killed effectively except germ, can also generate more halogenated hydrocarbon compound simultaneously, the contents of these chlorinated organics at
Increase again, is the significant source for causing the mankind to suffer from various diseases.Even boiling tap water, above-mentioned residue still drive no
It goes, the carcinogenic substances such as nitrite and chloroform can also increased.Also that is, even if the safety coefficient of drinking water is also not high
's.
Since direct drinking public water supply is difficult to ensure safety, water purifier comes into being, and becomes common people's hard requirement.However, existing
Using city for tap water as the purification of water quality product or drinking water related product of source water, essentially medium absorption or use various bore filters
Water pollutant is intercepted the physical treatment technology filtered out by film.Since active carbon class adsorbent material is easy to saturation failure,
And various filter membranes are easy to be contaminated by bacterial or organic matter obstruction or damaged, therefore actual conditions be can not be as theory is set
Meter is desired to be accomplished to the sufficiently cleaned up of water pollutant like that.It is existing to be adsorbed with medium in face of the source water pollution got worse
Or water pollutant is intercepted to the physics mode water treatment technology filtered out using various bore filter films and far can not
Guarantee water quality reaching standard.In addition, traditional RO membrane reverse osmosis filter method is very serious to the waste of water resource, 1 liter is often purified
Pure water just needs to be discharged 3 liters of concentration waste water.But physics mode water treatment technology also has its points of course: not generating poison usually
By-product.
In comparison, though Water Treatment technique has many advantages, such as being inexpensively simple and efficient, and it is unsuitable for civilian
Terminal Drinking Water field.To find out its cause, first is that the Water Treatment process requirement enough reaction time, and in daily life
With water occasion, water purifier is from booting water inlet to water outlet only several seconds or even shorter, and the residence time is too in water purifier for pollutant
It is short, have little time to complete related chemistry reaction treatment at all；The second is Water Treatment technique is usually made with certain poison is secondary
With.For example, although chemical oxidation reaction can potent inactivation of bacterial, depth degradation organic matter, go water removal in various harmful substances,
But the chemical oxidization method all kinds of Strong oxdiative factors generated are substantially non-selectivity, uncontrollable, if dealing with improperly most probably raw
The novel substance not having in Cheng Yuanshui even strong carcinogen, jeopardizes safe drinking water instead.And reduction reaction controls improper also bring along
Similar problems, such as nitrate may be converted into strong carcinogen nitrite；Just because of this, it is had no so far in Drinking Water
Purified treatment field especially family's drinking-water terminal promotes and applies.
Fortunately, in daily life, drinking water needs often have the characteristics that at times, interval.For example, family three times
Meal water and bathing peak are concentrated mainly on the time in the morning, afternoon and evening；Wash water then presses week/time calculating.Drinking water is deposited in daily life
Storage device leads to the drinking water terminal for referring to and having water tank (tank, container), such as: 1) pipeline water purification system terminal wall-hanger, desk-top
Or vertical drinking；2) RO water purification machine water outlet pressure store bucket (case) and water glass, pot；3) public supply mains high level is built
Build top layer installation high water tank in addition rural resident's groundwater abstraction to roof water tank.At present existing for such system
Common problem is that bacterial micro-organism is exceeded in water in water tank, and it is smelly to seriously affect water quality even peculiar smell.The solution that there is no so far
Certainly method.
Therefore, be badly in need of developing it is a kind of can satisfy home terminal drinking-water deep purifying requirement, with water storage container be anti-
Ying Chi, to source water to be intermittently discharged the easy device that working method is handled, every household is all afforded to use.
Summary of the invention
Present invention solves the technical problem that being, in view of the shortcomings of the prior art, proposing a kind of to the family in water container
Terminal drinking-water less generates toxic byproduct fixed sterile type when carrying out degradation Organic substance in water drinks water storage apparatus.
Applicant explores by repetition test and for many years, it was found that electrochemistry as a kind of advanced oxidation water treatment technology,
Attached poison seondary effect is small far beyond conventional chemical water treatment technology, and electro-chemical water treatment process can pass through electrical parameter
Adjustment carrys out intensive treatment intensity and reduces the reaction time.Overcome physics water treatment technology soft in this way, electrochemical water treatment technology has
Rib, the certain potentiality that can be used for Drinking Water purified treatment.
Electrochemical water treatment technology is to make polluter that Direct Electrochemistry reaction occur on the electrode or utilize electrode table
Face generates strong oxidizing property active material and oxidation reaction occurs and is converted electrochemical techniques and its is aided with other high-level oxidation technologies
Group technology, referred to as electrochemical system, including electrode electro-catalysis, electricity-Fenton, electricity-O3, sound-electric, optical-electronic etc..
Electro-chemical water processing be unable to do without electrode effect, is specifically divided into electrode and directly reacts and electrode indirect reaction.Electrode is straight
It is reversed to refer to that pollutant is directly oxidated or reduced on the electrode and removes from water.Direct Electrolysis can be divided into anodic process and
Cathodic process.Anodic process is exactly that pollutant aoxidizes in anode surface and is converted to the lesser substance of toxicity or easily biological-degradable
Substance, or even generation organic matter are inorganization, to achieve the purpose that reduction, removal pollutant.Cathodic process is exactly that pollutant exists
Cathode surface is restored and is removed.
Electrode indirect reaction is then to make to pollute using the redox materials of electrochemistry generation as reactant or catalyst
Object is converted to the smaller substance of toxicity.Anode indirect reaction, generated redox materials, generally include following several in water
Class: (1) with chlorate, the hypochlorite etc. of strong oxidizing property；Elecrtonegativity can be removed by anode；(2) H2O2、O3(standard electric
Electrode potential 2.07, half-life period 30-60min) etc. the Strong oxdiatives factor；(3) strong oxidizing property and service life that electrochemical reaction generates are extremely short
Intermediate, including e (solvated electron), OH, HO2·、·O2Equal free radicals can be with degradation of organic substances based on OH.
But still belong to chemical treatment technology in electrochemical nature, even toxic side effect is small again, still there are the Biological indicators for making water
The risk of reduction.Water environment it is unprecedented it is serious pollution, in conventional physical water purifier today unable to do what one wishes, examine closely again
Study Water Treatment --- especially electrochemical water treatment technology is a possibility that Drinking Water purified treatment is applied, innovation
Water pollutant, again the electrochemical treatments technique of non-toxic by-products or even electro-chemical water processing can efficiently be removed by developing one kind
Technique cooperateed with physisorptive filter technique associated with completely new method for purifying water and device, there is highly important reality meaning
Justice.
